The Wishbone String & Cable Dampeners will make a noticeable reduction of noise and vibration on your bow's string and cables. These easy-to-install dampeners do not require a bow press, so anyone can quickly add a set to their bow and instantly quiet their setup. At 14 grains each, the Wishbone will not slow your bow down, and in fact, can help increase speed. Comes in a pack of four dampeners.
